<P>PROBLEM TO BE SOLVED: To provide a paper tray not bulky even if stacked while maintaining sufficient strength and appearance. <P>SOLUTION: The paper tray 10 includes a bottom part 12, and wall parts 14 rising from the bottom part 12. The wall parts 14 are formed by bending a plurality of wall paper pieces 10a extending in four directions from the bottom part in the deployed state respectively, and comprise a first pair of wall parts 14A facing each other, and a second pair of wall parts 14B facing each other while overlapping with part of the first pair of wall parts 14A from above. Each wall part 14 has, at its top, an edge surface part 16 formed by bending the wall part paper piece 10a outward twice from the deployed state. Each wall part 14 rises inclining outward from the bottom part 12. In the assembled state of the wall parts 14, part of the first wall part paper pieces 10a1 and part of the second wall part paper pieces 10a2 are engaged with each other by the restoring force of the first and second wall part paper pieces 10a that are going to be restored into the deployed state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
